Automated network voice testing platform

ABSTRACT

A device initiates voice communication sessions with a media resource function processor (MRFP) of a network, where each voice communication session communicates audio data via one or more network devices of the network. For each voice communication session, the device sends first audio data to the MRFP and receives second audio data from the MRFP via the voice communication session, processes the first audio data and second audio data to determine one or more characteristics of the second audio data, and generates a record concerning the voice communication session based on the one or more characteristics of the second audio data. The device generates a report based on a respective record of each voice communication session, processes the report using an artificial intelligence technique to identify an issue concerning at least one network device, and performs, based on identifying the issue, an action concerning the at least one network device.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings can identify the same or similar elements.

A network, such as an LTE network, processes millions of voice communication sessions per hour. A voice communication session communicates audio data between two or more user devices. In some cases, a particular network device, of a plurality of network devices of the network, does not function properly and cannot facilitate the communication of audio data via the voice communication session. In such a case, unless the failure affects a large volume of voice communication sessions, current network diagnostic tools cannot identify an issue with the particular network device. Moreover, in order to maintain the privacy of users of the network, network monitoring tools typically do not monitor audio quality of the voice communication sessions. Accordingly, network administrators must rely on users' complaints and/or feedback to address issues concerning the quality of voice communication sessions.

Some implementations described herein provide a testing platform that is capable of testing one or more network devices of a network. In some implementations, the testing platform can initiate a plurality of communication sessions with a media resource function processor (MRFP) of a network. According to some implementations, for each voice communication session of the plurality of voice communication sessions, the testing platform can send first audio data to the MRFP and receive second audio data from the MRFP. In some implementations, the testing platform can process the first audio data and the second audio data to determine one or more characteristics of the second audio data to generate a record concerning the voice communication session. According to some implementations, the testing platform can generate a report based on a respective record of each voice communication session of the plurality of voice communication sessions. In some implementations, the testing platform can process the report to identify an issue concerning at least one network device of the one or more network devices, such as the at least one network device malfunctioning, occasionally not performing correctly, performing slowly, and/or the like. In some implementations, the testing platform can perform an action to address the issue concerning the at least one network device.

In this way, some implementations described herein can automatically identify an issue concerning at least one network device of a network and automatically perform a corrective action to address the issue. This conserves resources of the network that would otherwise be used to compensate for a malfunctioning network device, reduces the amount of time a technician would have to spend identifying, diagnosing, and/or repairing the malfunctioning network device, and reduces costs associated with maintaining the network. Moreover, regularly testing network devices of the network can decrease a mean time to detect (MTTD) a network device issue, which would take longer to detect using traditional monitoring functions (e.g., such as receiving communications from users regarding voice communication session quality issues). This can result in more efficient operation of the network and/or a better user experience for users utilizing the network.

Moreover, some implementations described herein, can automatically identify an issue concerning at least one network device of a production network during peak usage hours, rather than a production network during a maintenance window (e.g., during non-peak usage hours). In this way, the production network can be tested under a normal user load to emulate real-world user experiences. In this way, the testing platform can identify issues (e.g., high processor utilization issues, network transport congestion issues, and/or the like) that would not be identified on the production network during a maintenance window with a lower volume of voice communication sessions. Further, some implementations can take a “do no harm” approach to testing the production network, such that the testing platform limits (e.g., by implementing physical limitations and software safeguards) the number of voice communication sessions that the testing platform can initiate over a period of time. For example, the facilitation platform can limit the number of test voice communication sessions (e.g., only 120 thousand test communications sessions per hour) so as to only be a fraction of the number of production communication sessions over the period of time (e.g., 25 million production communication sessions per hour), which can prevent the testing platform from detrimentally impacting the functionality of the production network during testing.

Furthermore, the process for identifying or determining an issue concerning a network device is automated, and the testing platform can identify or determine numerous (e.g., hundreds, thousands, millions, and/or the like) issues at roughly the same time. This improves speed and efficiency of the process and conserves computing resources (e.g., processor resources, memory resources, power resources, and/or the like) of the testing platform and/or network. Furthermore, implementations described herein use a rigorous, computerized process to perform tasks or roles that were not previously performed or were previously performed using subjective human intuition or input. For example, currently there does not exist a technique to automatically determine and address an issue concerning a network device of a plurality of network devices based on communicating audio data via a voice communication session. Finally, automating the process for determining and addressing an issue concerning a network device of a plurality of network devices conserves computing resources (e.g., processor resources, memory resources, power resources, and/or the like) that would otherwise be wasted in attempting to assist a human in determining and addressing an issue concerning a network device of a plurality of network devices by hand.

FIGS. 1A-1C are diagrams of an example implementation 100 described herein. As shown in FIGS. 1A-1C, example 100 can include a testing platform (e.g., one or more devices capable of receiving, generating, storing, processing, and/or providing audio data) and a media resource function processor (MRFP) that processes media streams, such as audio streams, and transcodes multimedia data, such as audio data. In some implementations, the MRFP can be associated with an Internet Protocol (IP) Multimedia Subsystem (IMS core) of a network, such as an IMS core of a Long-Term Evolution (LTE) network. Some example implementations described herein concern a single testing platform and/or a single MRFP, but some implementations can include a plurality of testing platforms and/or a plurality of MRFPs. For example, an LTE network can be divided into a plurality of open shortest path first (OSPF) areas, where an OSPF area can be associated with an IMS core that can have a plurality of MRFPs. Further, a plurality of testing platforms can be associated with the plurality of OSPF areas such that a particular testing platform of the plurality of testing platforms is associated with at least one particular OSPF area of the plurality of OSPF areas.

As shown in FIG. 1A and by reference number 102, the testing platform can initiate a voice communication session with the MRFP. In some implementations, the testing platform can emulate a user device and other devices of the network, such as a call session control function (CSCF), a home subscriber server (HSS), a user profile server function (UPSF), a subscription locator function (SLF), a breakout gateway control function (BGCF), a media gateway controller function (MGCF), a media gateway (MGW), a signaling gateway (SGW), and/or the like of the IMS core to initiate the voice communication session with the MRFP. In this way, the testing platform can initiate a voice communication session by directly connecting to the IMS core of the network, which enables the testing platform to connect with a particular MRFP of the IMS core, without having to connect to the network and/or the IMS core via a base station, a radio access network (RAN), an evolved packet core (EPC), and/or the like. This conserves processing resources, memory resources, and/or power resources of the testing platform, as well as resources of the network, that would otherwise be used to initiate and maintain the communication session via the base station, the RAN, the EPC, and/or the like. Some example implementations described herein concern a single testing platform initiating a single voice communication session with an MRFP, but some implementations can include a single testing platform initiating a plurality of voice communication sessions with the MRFP, initiating a plurality of voice communication sessions with a plurality of MRFPs, and/or the like. Further, some implementations can include a plurality of testing platforms initiating a plurality of voice communication sessions with a plurality of MRFPs and/or the like.

In some implementations, a voice communication session can communicate audio data between the testing platform and the MRFP. In some implementations, the voice communication session can communicate the audio data via one or more network devices of the network, such as routers, firewalls, gateways, servers, base stations, access points, and/or the like. In some implementations, the audio data can include voice data, such as human speech.

In some implementations, the testing platform can initiate the voice communication session with the MRFP by sending a session initiation protocol (SIP) message to a media resource function controller (MRFC) associated with the MRFP. In some implementations, the MRFC can cause the MRFP to establish the voice communication session with the testing platform based on the SIP message. In some implementations, the SIP message can indicate that the testing platform is a source and a destination of the voice communication session (e.g., such that the audio data is communicated from the testing platform to the testing platform via the MRFP). In some implementations, the SIP message can indicate that the voice communication session should be routed via a particular OSPF area, a particular node (e.g., a group of MRFPs and/or MRFCs), a particular MRFP and/or a particular MRFC, and/or the like.

In some implementations, the testing platform can determine a topology of the network (e.g., determine how components of the network, such as MRFPs, MRFCs, other network devices, and/or the like are connected) and determine and/or generate scripts to automatically initiate voice communication sessions to a particular OSPF area, a particular node (e.g., a group of MRFPs and/or MRFCs), a particular MRFP and/or a particular MRFC, a particular network device, and/or the like. For example, the testing platform may generate a script to automatically initiate a set of voice communication sessions to an OSPF, such that the set of voice communication sessions is created to test all MRFCs, MRFPs, and/or network devices of the OSPF. In this way, the testing platform can control which OSPF areas, nodes, MRFPs, MRFCs, and/or network devices the testing platform tests via the voice communication sessions. In some implementations, the testing platform can cause the scripts to run on a scheduled basis (e.g., every 12 hours, every day, every week, and/or the like), an on-demand basis (e.g., a network administrator instructs the testing platform to run the scripts), a triggered basis (e.g., a threshold amount of users complain about voice communication sessions in a particular OSPF area), and/or the like.

In some implementations, the testing platform can utilize one or more safeguards to prevent overloading of the MRFP, the IMS core, the network, and/or the like when initiating a plurality of voice communication sessions with an MRFP. For example, the testing platform can determine a maximum number of voice communication sessions with the MRFP that can be established in a period of time (e.g., a maximum number of voice communication sessions that can be established with the MRFP without overloading the MRFP, the IMS core, the network, and/or the like). The testing platform can limit a number of the plurality of voice communication sessions to initiate during the period of time to be less than the maximum number of voice communication sessions. As another example, the testing platform can determine a maximum bandwidth allotment for voice communication sessions with the MRFP for the period of time (e.g., a maximum amount of audio data that can be communicated with the MRFP without overloading the MRFP, the IMS core, the network, and/or the like). The testing platform can limit the number of the plurality of voice communication sessions to be initiated during the period of time such that the total bandwidth associated with the number of the plurality of voice communication sessions is less than the maximum bandwidth allotment for voice communication sessions. In some implementations, the testing platform can determine the number of the plurality of voice communication sessions to initiate during the period of time based on the maximum number of voice communication sessions and the maximum bandwidth allotment.

As shown in FIG. 1B and by reference number 104, the testing platform can send first audio data to the MRFP. In some implementations, the testing platform can send the first audio data to the MRFP via the voice communication session. In some implementations, the first audio data can include test voice data (e.g., a recording of a human speaking for a period of time, such as twenty seconds, one or more humans speaking for the period of time, one or more humans having a conversation for the period of time, and/or the like). In some implementations, the testing platform can send the first audio data to the MRFP via one or more network devices via the voice communication session. In some implementations, the one or more network devices can include a router (such as an optical transport network router), a firewall, a gateway, a server, an access point, and/or the like of the network and/or the IMS core.

As shown by reference number 106, the MRFP receives and processes the first audio data. For example, the MRFP can process the first audio data using a digital signal processor (DSP) of the MRFP. In some implementations, the MRFP can transcode and/or convert the first audio data into second audio data. For example, where the first audio data conforms to a first voice protocol, such as the Pulse Code Modulation (PCM) voice protocol (e.g., the ITU Telecommunication Standardization Sector (ITU-T) G.711 voice protocol), the MRFP can convert the first audio data into the second audio data that conforms to a second voice protocol, such as the Adaptive Multi-Rate Wideband (AMR-WB) voice protocol (e.g., the ITU-T G.722.2 voice protocol). In this way, the MRFP can function in a way that tests real-world functionality, where the MRFP has to transcode and/or convert audio data so that two different types of user devices that use different voice protocols can communicate. In some implementations, the testing platform can send an SIP conversion signal to the MRFC to cause the MRFP to convert and/or transcode the first audio data into the second audio data. In some implementations, the MRFP can transcode and/or convert the first audio data into the second audio data such that the test voice data is included in the second audio data.

As shown by reference number 108, the MRFP can send the second audio data to the testing platform. In some implementations, the second audio data can include the test voice data that was part of the first audio data. In some implementations, the MRFP can send the second audio data to the testing platform via the voice communication session. In some implementations, the MRFP can send the second audio data to the testing platform via the one or more network devices via the voice communication session. In some implementations, the testing platform can receive the second audio data from the MRFP.

As shown by reference number 110, the testing platform can determine one or more characteristics of the second audio data. In some implementations, the testing platform can process the first audio data and the second audio data to determine the one or more characteristics of the second audio data. In some implementations, the testing platform can analyze the test voice data of the second audio data to determine the one or more characteristics of the second audio data. In some implementations, the one or more characteristics of the second audio data can include a packet loss performance of the second audio data. For example, the testing platform can determine that a percentage (or number) of packets of the second audio data are missing when compared to packets of the first audio data. In some implementations, the packets of the second audio data can be empty, which can indicate a “one way audio” error (e.g., that audio data is communicated in an outgoing direction but not an incoming direction). In some implementations, the one or more characteristics of the second audio data can include: a jitter of the second audio data (e.g., a delay between the packets of the second audio data); a mean opinion score (MOS) of the second audio data (e.g., a quality rating of the second audio data); a latency of the second audio data (e.g., a delay in transmission of packets of the second audio data from the MRFP to the testing platform); a wave form deviation of the second audio data (e.g., an impact to a sample rate, frequency range, power, fidelity, and/or the like of the second audio data); and/or the like.

As shown by reference number 112, the testing platform can generate a record concerning the voice communication session based on the one or more characteristics of the second audio data. In some implementations, the record can include information concerning the one or more characteristics of the second audio data. Some example implementations described herein concern a single testing platform generating a single record, but some implementations can include a single testing platform generating a plurality of records concerning a plurality of voice communication sessions, a plurality of testing platforms generating a plurality of records concerning a plurality of voice communication sessions, and/or the like.

As shown in FIG. 1C and by reference number 114, the testing platform can generate a report based on the plurality of records concerning the plurality of voice communication sessions. In some implementations, the testing platform can generate the report based on a respective record of each voice communication session of the plurality of voice communication sessions. In some implementations, the testing platform can compile the plurality of records into the report.

As shown by reference number 116, the testing platform can determine and/or identify one or more issues concerning an MRFP, an MRFC, one or more network devices and/or the like. In some implementations, the testing platform can process the report using an artificial intelligence technique to determine and/or identify the issue concerning the MRFP, the MRFC, at least one network device, and/or the like. For example, the testing platform can identify a set of bad voice communication sessions, determine a set of MRFPs, MRFCs, network devices, and/or the like associated with the set of bad voice communication sessions, and use the artificial intelligence technique to determine that a particular MRFP, MRFC, network device, and/or the like has an associated issue. In some implementations, the testing platform can utilize a machine learning model to determine and/or identify the issue concerning the MRFP, the MRFC, the at least one network device, and/or the like.

In some implementations, the testing platform can generate, train, retrain, update, and/or the like the machine learning model using a machine learning technique. For example, the testing platform can process historical records from historical reports to generate and/or train a machine learning model. In some implementations, the testing platform can process the historical records to train the machine learning model to determine and/or identify an issue concerning an MRFP, an MRFC, at least one network device, and/or the like.

In some implementations, the testing platform can perform a set of data manipulation procedures to process the historical records to generate the machine learning model. Examples of data manipulation procedures include: a data preprocessing procedure, a model training procedure, a model verification procedure, and/or the like. For example, the testing platform can preprocess the historical records to remove numbers and/or letters, non-ASCII characters, other special characters, white spaces, confidential data, and/or the like. In this way, the testing platform can organize thousands, millions, or billions of data entries for machine learning and model generation—a data set that cannot be processed objectively by a human actor.

In some implementations, the testing platform can perform a training operation when generating the machine learning model. For example, the testing platform can portion the historical records into a training set, a validation set, a test set, and/or the like. In some implementations, the testing platform can train the machine learning model using, for example, an unsupervised training procedure and based on the training set of the data. In some implementations, the testing platform can further train the machine learning model using the validation set and test the machine learning model using the test set. In some implementations, the testing platform can perform dimensionality reduction to reduce the historical records to a minimum feature set, thereby reducing processing to train the machine learning model, and can apply a classification technique to the minimum feature set.

In some implementations, the testing platform can use a logistic regression classification technique to determine a categorical outcome (e.g., that particular historical records are associated with particular issues). Additionally, or alternatively, the testing platform can use a naïve Bayesian classifier technique. For example, the testing platform can perform binary recursive partitioning to split the data of the minimum feature set into partitions and/or branches, and use the partitions and/or branches to perform predictions (e.g., that particular historical records are associated with particular issues). Based on using recursive partitioning, the testing platform can reduce utilization of computing resources relative to manual, linear sorting and analysis of data points, thereby enabling use of thousands, millions, or billions of data points to train the machine learning model, which can result in a more accurate machine learning model than using fewer data points.

Additionally, or alternatively, the testing platform can use a support vector machine (SVM) classifier technique to generate a non-linear boundary between data points in the training set. In this case, the non-linear boundary is used to classify test data (e.g., particular historical records) into a particular class (e.g., a class indicating that the particular historical records are associated with particular issues).

Additionally, or alternatively, the testing platform can train the machine learning model using a supervised training procedure that includes receiving input to the model from a subject matter expert, which can reduce an amount of time, an amount of processing resources, and/or the like to train the machine learning model, relative to an unsupervised training procedure. In some implementations, the testing platform can use one or more other model training techniques, such as a neural network technique, a latent semantic indexing technique, and/or the like. For example, the testing platform can perform an artificial neural network processing technique (e.g., using a two-layer feedforward neural network architecture, a three-layer feedforward neural network architecture, and/or the like) to perform pattern recognition with regard to patterns of particular historical records that are associated with particular issues. In this case, using the artificial neural network processing technique can improve an accuracy of the machine learning model generated by the testing platform by being more robust to noisy, imprecise, or incomplete data, and by enabling the testing platform to detect patterns and/or trends undetectable to human analysts or systems using less complex techniques.

Accordingly, the testing platform can use any number of artificial intelligence techniques, machine learning techniques, deep learning techniques, and/or the like to determine and/or identify an issue concerning an MRFP, an MRFC, at least one network device, and/or the like.

As shown by reference number 118, the testing platform can perform a corrective action. In some implementations, the testing platform can perform, based on determining and/or identifying the issue concerning the MRFP, the MRFC, the at least one network device, and/or the like, an action to address the issue. In some implementations, the action can concern the MRFP, the MRFC, the at least one network device, and/or the like. In some implementations, the action can include causing the MRFP, the MRFC, the at least one network device, and/or the like to be disconnected from the network. This improves the operation of the network by physically removing the MRFP, the MRFC, the at least one network device, and/or the like from negatively impacting the network. In some implementations, the action can include causing audio data to be diverted around the MRFP, the MRFC, the at least one network device, and/or the like. This improves the operation of the network by functionally removing the MRFP, the MRFC, the at least one network device, and/or the like from negatively impacting the network. This also improves the operation of the network by increasing voice communication session traffic to devices that are performing well and by reducing voice communication session traffic to devices that are not performing well.

In some implementations, the action can include determining a set of instructions to correct the issue. In some implementations, the testing platform can execute the set of instructions to correct the issue (e.g., cause the MRFP, the MRFC, the at least one network device, and/or the like to be disconnected from the network, cause audio data to be diverted around the MRFP, the MRFC, the at least one network device, and/or the like). This improves the operation of the network by physically, functionally, and/or the like removing the MRFP, the MRFC, the at least one network device, and/or the like from negatively impacting the network. This also reduces the need for a technician to physically service the MRFP, the MRFC, the at least one network device, and/or the like, which reduces the amount of service technicians that are needed to maintain the network, which reduces costs associated with maintaining the network. In some implementations, the testing platform can generate a message that includes the set of instructions and information that identifies the issue and/or the MRFP, the MRFC, the at least one network device, and/or the like. In some implementations, the testing platform can send the message to a remote device (e.g., a user device of a service technician). In some implementations, the remote device can display the set of instructions and the information that identifies the issue and/or the MRFP, the MRFC, the at least one network device, and/or the like. In this way, the service technician that uses the remote device has information to efficiently address the issue without having to run diagnostic tests on the MRFP, the MRFC, the at least one network device, and/or the like. This can reduce the amount of time that the service technician has to spend on servicing the MRFP, the MRFC, the at least one network device, and/or the like, which can reduce costs associated with maintaining the network.

In some implementations, the action can include running a diagnostic test on the MRFP, the MRFC, the at least one network device, and/or the like. For example, the testing platform can isolate an individual element of the MRFP, the MRFC, the at least one network device, and/or the like, and perform tests on the individual element (e.g., send signals, SIP messages, audio data, and/or the like to the individual element) to identify or determine one or more issues concerning the individual element. In some implementations, the individual element can include an audio codec, a voice card, an Ethernet voice port, a SIP signaling port, and/or the like. In some implementations, the testing platform can cause, based on identifying/determining the one or more issues concerning the individual element, the individual element and/or the MRFP, the MRFC, the at least one network device, and/or the like to be serviced. In this way, the testing platform can automatically diagnose and address the issue. This can reduce the amount of time that the service technician has to spend on servicing the MRFP, the MRFC, the at least one network device, and/or the like, which can reduce costs associated with maintaining the network.

In some implementations, the testing platform can send information identifying the issue to an additional device (e.g., a user device configured to run diagnostics on an MRFP, an MRFC, at least one network device, and/or the like). In some implementations, the additional device, based on the information identifying the issue, can run the diagnostic test on the MRFP, the MRFC, the at least one network device, and/or the like and send a diagnostic report to the testing platform. In some implementations, the testing platform can cause, based on the diagnostic report, the MRFP, the MRFC, the at least one network device, and/or the like to be serviced. This can reduce the amount of time that the MRFP, the MRFC, the at least one network device, and/or the like needs to be serviced, which can reduce the need for redundant MRFPs, MRFCs, network devices, and/or the like in the network, which can reduce maintenance costs associated with servicing the redundant MRFPs, MRFCs, network devices, and/or the like in the network.

In some implementations, the first audio data can conform to a first voice protocol and the second audio data can conform to a second voice protocol.

In some implementations, when initiating the plurality of voice communication sessions with the MRFP of the network, the testing platform can determine a maximum number of voice communication sessions with the MRFP that can be established in a period of time, can determine a maximum bandwidth allotment for voice communication sessions with the MRFP for the period of time, can determine a number of the plurality of voice communication sessions to initiate during the period of time based on the maximum number of voice communication sessions and the maximum bandwidth allotment, and can initiate, based on determining the number of the plurality of voice communication sessions to initiate during the period of time, the plurality of voice communication sessions with the MRFP during the period of time.

In some implementations, when performing the action concerning the MRFP or the at least one network device, the testing platform can determine a set of instructions to correct the issue, can generate a message that includes the set of instructions and information that identifies the issue and the MRFP or the at least one network device, and can send the message to a remote device having a display, where sending the message to the remote device causes the remote device to display the set of instructions and the information that identifies the issue and the MRFP or the at least one network device. In some implementations, when performing, based on identifying the issue, the action concerning the MRFP or the at least one network device, the testing platform can cause the MRFP and/or the at least one network device to be disconnected from the network, and/or can cause audio data to be diverted around the MRFP or the at least one network device.
